We have a build in test flight where field testing is going on, it has UIWebView so once it passes the testing can this same build submitted for approval. Will Apple approve the build or reject it?
But if you're asking for a pre-review, remember, those are not made, app review isn't here and no one here can promise what review will/won't approve/reject.
My advice is if you want to avoid wasting time due to the 4 month old announcement and 10-day deadline last minute risk, don't take it. Otherwise, go for it and let us know how it works out.
